The reviewer found it straightforward to install and dependable in operation, making it a practical choice for maintenance techs and DIYers who want an exact fit without modifying the system. The single most compelling reason to buy is the factory-spec switching points, which restore correct cycling to compressors that use the D075HPV5(LP), D1500HPV5(LP) or OD1500HPV5 models.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM part #:\u003c\/strong\u003e PS2020M provides an original equipment replacement that matches factory specifications and reduces compatibility guesswork.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure range:\u003c\/strong\u003e Cuts in at 105psi and cuts out at 135psi which restores correct compressor cycling for systems designed to operate in that window.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorting:\u003c\/strong\u003e Single 1\/4' male port and a 1\/4' compression fitting for the check valve unloader line make plumbing to the existing hoses straightforward.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManual lever:\u003c\/strong\u003e The manual on\/off switch lever allows simple system testing and manual shutdown during maintenance or troubleshooting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel fit:\u003c\/strong\u003e Designed to fit D075HPV5(LP), D1500HPV5(LP) and OD1500HPV5 models so installers can replace the switch without adapter parts.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe PS2020M is best for owners and technicians maintaining ROLAIR compressors that list D075HPV5(LP), D1500HPV5(LP) or OD1500HPV5 as compatible models.
